DAGVz Paper at Visual Performance Analysis Workshop

An Huynh will be presenting a paper on the visualization of task-parallel programs at the Visual Performance Analysis workshop at Supercomputing 2015.  (He is a student of Kenjiro Taura at the University of Tokyo who spent a semester working with us in the Cooperative Computing Lab.)

An developed DAGViz, a tool for exploring the rich structure of task parallel programs, which requires associating DAG structure with performance measures at multiple levels of detail.  This allows the analyst to zoom in to trouble spots and view exactly where and how each basic block of a program ran on a multi-core machine.
